摘要： A casting mold making apparatus and a method employing a tank with a pour hole formed passing through a bottom wall of the tank and an opening section formed to open toward the opposite side to a bottom wall side. The method includes executing a first process and a second process. The first process includes stirring component materials inside the tank with a stirring impeller so as to make a foam mixture in a state in which an opening section side of the tank is closed by a lid member and the pour hole is closed by a pour-hole closure mechanism. The second process is performed after the first process and includes actuating the pour-hole closure mechanism to open the pour hole, pressing the tank against a mold such that a fill hole formed so as to pass into the mold is disposed adjacent to the pour hole, and supplying compressed air into the tank while stirring the foam mixture inside the tank with the stirring impeller so as to fill the foam mixture inside the tank into a cavity of the mold.

摘要： The sand mixing device (1) has a mixing bowl (2) arranged stationarily on a support frame (3) and including a peripheral side wall (4) and a bottom wall (5). A central mix- ing tool (6) is arranged rotatably about a central mixer axis (7) of the mixing bowl and has a number of blades (8) extending along the bottom wall to the peripheral side wall. The mixing bowl is arranged in an inclined position on the support frame so that the central mixer axis is inclined at an angle to the vertical. A first cross-sectional plane extending through the mixing bowl and including both the central mixer axis and a horizontal line extending in a plane defining the bottom wall divides the mixing bowl into a lower part and a higher part. At least one peripheral mixing tool (9, 11) is arranged in the lower part of the mixing bowl.

摘要： The object of the invention is to provide a machine for disintegrating balls in molding sand that is not high, to avoid a high space being required for installing it. The machine maintains the performance of an aeration-type molding machine. The object is also to provide a system for supplying molding sand that saves the space for installing it and facilitates the maintenance of it. The machine for disintegrating balls in molding sand comprises a first bar for disintegrating the balls that is supported at both ends. The bar has a plurality of blades that radiate from a rotating shaft. The machine also comprises a second bar for disintegrating the balls that is supported on the common plane horizontal with, parallel to, and at a certain distance from, the first bar. The second bar rotates in a reverse direction from that of the first bar. When molding sand is loaded from above to a space between the first and second bar the balls are disintegrated while the molding sand is downwardly combed. The system for supplying molding sand is characterized in that the bars are supported by the frame of the carriage and in that the motors for rotating the bars are mounted on the carriage.

摘要： The invention relates to a molding sand cooler having a sand chamber which has an air inlet, if necessary comprising a fan, for the supply of air into the sand chamber, and an air outlet, if necessary comprising a fan, for the extraction of air from the sand chamber. The problem addressed by the invention is that of providing an improved molding sand cooler in which the discharge of sand via the air outlet during the cooling operation is reduced considerably. This problem is solved in that a dynamic air separator that is rotatable about an axis is provided, which air separator is arranged in such a way that substantially the whole air stream leaving the sand chamber through the outlet is guided through the dynamic air separator.
